Sir Isaac Newton



Isaac Newton was one of the first people to explain motion and gravity as a law. He invented many things from integral calculus, light particles, and even a reflecting telescope. Issac Newton was appointed warden of Mint: and later appointed master of Mint for which he sat in parliament from 1689-1690. He became president of the Royal Society in 1703 and in 1705. Newton had the honor of being knighted by Queen Anne. Issac Newton developed an interest in Mathmatics and the law of nature which led to his works called Philosophiae Naturalis Principia Mathematica (1687) and Opticks ยน.

Insight and influences



During the time Newton was alive, many events were taking place for change. Galileo died in 1642 leaving his legacy as to where the sun was the center of the solar system rather than the earth. In 1672 the Puritans settled in Pennsylvania where they were called Quakers. Quakers came to America because they were persectued by England and became the dominant religion in Pennsylvania until 1756. Johann Sebastian Bach, a German musician, was busy studying the construction of the organ and was recognized for his uncommonly beautiful soprano voice. During the years of 1672 to 1725 Peter the Great lived a colorful life dragging Russia out of the medievil times until Russia was considered the premier eastern european state. The Salem Witch Trials in 1692 were a series of dark events that arose in the town of Salem Village, Massachusetts. Young girls were said to be visited by a devil spirit and had strange behaviors and trance like states. In the end, eighteen were hanged, one was crushed by the weight of stones and three died in prison awaiting a sham trial. Amongst all this disorder, Newton made the radical proposal of a "clockwork" Universe, one run precisely by the force of gravity. After Newtons death, Albert Einstein validated Newton's work and proved that the universe was a wider, more fantastical and more unpredictable place than Newton had thought possible (parenthetical-spark notes).


Major Contributions



"Newton's Law of Universal Gravitation has been described as follows: It is a force between any two bodies and is "directly proportional to the product of their masses and inversely proportional to the square of the distance between them. ... The measure of the force of gravitation on a given body on earth is the weight of that body." While certain of Newton's theories have not stood the tests applied in the 20th century, his law of universal gravitation has stood: "In the general theory of relativity, gravitation is explained geometrically: matter in its immediate neighborhood causes the curvature of the four-dimensional space-time continuum." Newton showed that around the Earth gravitational force was being applied so everything wouldnt just fly away instead it stayed on the ground. This was known as the Law of Gravity.In this work, Newton showed how his principle of universal gravitation explained both the motions of heavenly bodies and the falling of bodies on earth. "Everybody continues in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed upon it. ... The change of motion is proportional to the motive force impressed; and is made in the direction of the right line in which that force is impressed. ... [and] To every action there is always opposed an equal reaction: or, the mutual actions of two bodies upon each other are always equal, and directed to contrary parts." This was known as the Law of Motion.

Background



Newton was born on Christmas day in the village of Lincolnshire, England where he grew up reading for hours a day and recording everything that interested him. His boyhood inventions branched from various interests like creating sundials, an accurate wooden clock, water wheels, and even a kite with an enclosed lantern, which fooled the locals into seeing ghosts. One of his most practical adolescent inventions was a mill, which mechanically ground wheat into flour via mouse power (parentetical). Newtons father past away before Newton was even born. His uncle saw his potencial in science and therefore enrolled him into Cambridge University where he was introduced to the world of mathematics and science. Newton soon mastered Descartes' difficult work, Geometry. After that point Newton's hunger for math and science grew to a maximum. "At the end of his second year at Cambrigde, Newton took the place of his professor, Dr. Isaac Barrow, who resigned in recognition of Newton's superior mathematical skills"(parenthetical). In 1664, the Great Plague struck England and closed the school so the Professiors and students wouldn't be exposed to the disease. During the years of 1664 and 1666 Isaac made his greatest contributions to mathematics. "Relying on the works of Galileo, Kepler, and Descartes, Newton invented calculus, discovered the law of universal gravitation, and he did extensive work on spectrums. The creation and development of his calculus was said to be the first achievement of mathematics, however, Newton would not publish his calculus until much later in his life "(parenthetical). The next twenty years Newton's mathematics advanced so far that mathematicians who spent 50 years trying to understand them could not comprehend Newton's findings. "In 1684, Newton began writing Principia or Mathematical Principles of Natural Philosophy, to help summarize his discoveries about the physical world. He formulated the three laws of motion, the third of which is essential to the understanding of modern rocket power and jet propulsion. Furthermore, he discussed the motion of bodies in free space, the motion of bodies in a resisting medium, and the solar system and celestial movements" (parenthetical). During his writing, he spent 18 to 19 hours of writing the book ignoring everything in the outside world; getting very little sleep and eating less. "In addition to Principia, Newton wrote The Universal Arithmetic, which help to substantiate and advance his theory of equations. He also wrote papers concerning calculus, curves, optics, and analytical geometry. Again many of these works went unpublished until long after they were written" (parenthetical). During the time he didnt publish his calculus works a German mathematician named Leibiniz had created an identical mathematical work to calculus and published these results in Germany in 1684, Leibiniz was referred to as calculus' creator. When word got around to England, Newton became enraged. In the end, France used both Newton's and Leibiniz's works at their universities. Newton never married nor had any children but lived well due to several wealthy patrons. He would spent hours solving a problem and then send them to his peers. He spent the remainder of his life as Master of the Mint in England, in honor of his service to his country (parenthetical). Newton died in London at the age of 85 where he was buried in Westminster Abbey.

The Things he left behind


After Newton's death, many of his observations led to new and brighter scientific theories. He unified many of the isolated physics work that had been discovered earlier into a satisfying system of laws (parenthetical). His laws of motion provoked a wide variety of scientific and engineering situations. Newton contributed to our understanding of how the universe works and behaves is an influence even to this day. By collecting the ideas of those before him, Newton created one of science's great unified thoeries and devised laws that sweepingly explained the persistent problem of planetary motion (parenthetical). Newton is considered to this day one of the greatest scientists that has ever lived.
